I have been using this paper in my office for three years now and use about three boxes a month.. I have never had a problem with it jamming in the machines or any ink running. I would also say that the paper is very professional both looking and feeling. The paper appears to be made of a nice high quality and the price is extremely reasonable compared to the papers for selection. The only complaint I would have its the packaging and there no handles to carry the boxes with the and straps cut your hands.
